Sending data DHT11 using a LoRa Shield and Arduino Uno doesnt work

[Philipp1807]

Hello everyone,

I am a little helpless. In my opinion, my code would have to be correct to send the data from the DHT11 sensor to TheThingsNetwork. ABP is used. However, I do not receive any data in the TTN Console. The serial monitor displays: Beginning Humidity: 0 13: 21: 35,474 -> Temperature: 0 13: 21: 35.474 -> 17159: EV_JOINING

For help, I would be grateful. Here is my code:
